I'm making an application, in this application I have edit text. I want when user write some text in edit text end then press enter button, I want it call some command. This what i have been done. This is work in ICS, but when I try on other device (Jelly Bean) it doesn't work.

inputViaTextChatbot.setOnEditorActionListener(new OnEditorActionListener() {
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            if ((event != null && (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) || (actionId == EditorInfo.IME_ACTION_DONE)) {
                // hide the keyboard  
                InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);  
                imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
                // process 
                getThis = inputViaTextChatbot.getText().toString();
                if (getThis!=null && getThis.length()>1) {  
                    try {
                    Log.v("Got This: ", getThis);
                    } catch (IllegalStateException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }

                    inputViaTextChatbot.setText("");  
                }
            }    
            return false;
        }
    });

谁能帮助我做到这一点？

推荐答案

这是一个已知的bug，使输入键不能在多个设备识别。一种解决方法，以避免它，并让它工作将是以下内容：

This is a known bug that makes the Enter key not be recognized on several devices. A workaround to avoid it and make it work would be the following:

创建一个 TextView.OnEditorActionListener 是这样的：

TextView.OnEditorActionListener enterKey = new TextView.OnEditorActionListener() {
  public boolean onEditorAction(TextView view, int actionId, KeyEvent event) {
    if (actionId == EditorInfo.IME_ACTION_GO) {
      // Do whatever you need
    }
    return true;
  }
};

假设你的查看是的EditText ，例如，你需要将其设置这种方式：

Assuming your View is an EditText, for instance, you'd need to set it this way:

final EditText editor = (EditText) findViewById(R.id.Texto);
editor.setOnEditorActionListener(enterKey);

最后一步走的是分配以下属性添加到的EditText ：

android:imeOptions="actionGo"

这基本上改变了回车键的默认行为，将其设置为 actionGo 输入法选项。在您的处理程序只分配它，你所创建的监听器和这种方式，您将有回车键的行为。

This basically changes the default behavior of the enter key, setting it to the actionGo IME option. In your handler simply assign it the listener you've created and this way you'll have the enter key behavior.
